Abstract
A molecular dynamics study of the motion of dislocations in aluminum containing hardening copper precipitates is carried out. The paper considers the interaction of dislocation with four types of precipitates, the structure of which was determined in experimental work. The energy of dislocation segments attached to hardening phases is determined and used as a parameter of the continuum model of the dislocation-precipitate interaction. An increase in energy is observed for hybrid precipitates compared to non-hybrid ones.
